◆ APR_ENCODE_BASE32HEX

#define APR_ENCODE_BASE32HEX   8

Generate base32hex encoding instead of base32 encoding

Definition at line 135 of file apr_encode.h.

◆ APR_ENCODE_BASE64URL

#define APR_ENCODE_BASE64URL   (APR_ENCODE_NOPADDING | APR_ENCODE_URL)

Generate RFC7515 BASE64URL

Definition at line 130 of file apr_encode.h.

◆ APR_ENCODE_COLON

#define APR_ENCODE_COLON   16

Generate base16 with colons between each token.

Definition at line 140 of file apr_encode.h.

◆ APR_ENCODE_LOWER

#define APR_ENCODE_LOWER   32

Definition at line 145 of file apr_encode.h.

◆ APR_ENCODE_NONE

#define APR_ENCODE_NONE   0

Definition at line 110 of file apr_encode.h.

◆ APR_ENCODE_NOPADDING

#define APR_ENCODE_NOPADDING   2

Definition at line 120 of file apr_encode.h.

◆ APR_ENCODE_RELAXED

#define APR_ENCODE_RELAXED   1

If relaxed, decode up until the first non base16/base32/base64 character.

Definition at line 115 of file apr_encode.h.

◆ APR_ENCODE_STRING

#define APR_ENCODE_STRING   (-1)

RFC4648 and RFC7515 compliant BASE64, BASE64URL, BASE32, BASE32HEX and BASE16 encode/decode functions.

The following encodings are supported:

If a non valid character of any kind including whitespace is passed to any of the decoder functions, APR_BADCH will be returned. In this case decoding will still take place, but the results can not be trusted.

If APR_ENCODE_RELAXED is passed to the decoder functions, decoding will be attempted up until the first non valid character. If this results in an invalid state in the decoder, such as but not limited to an odd number of base16 characters, APR_BADCH will still be returned.

If APR_ENCODE_RELAXED is not passed to a decoder function, the decoding will be done in constant time regardless of whether the result returns APR_SUCCESS or APR_BADCH.

If the dest parameter is NULL, the maximum theoretical buffer size is returned in the len field, including space for a terminating zero character if the destination is a string. This value can be used to allocate buffers of a suitable safe size.

If the dest parameter is provided, the encoding or decoding will take place, and the actual number of characters written is returned in the len field, ignoring any terminating zero.

Plain strings are not assumed '\0' terminated unless APR_ENCODE_STRING is provided. When passing a string to one of the encode functions, this value can be passed to indicate a string-valued key, and have the length computed automatically.

Definition at line 105 of file apr_encode.h.

◆ APR_ENCODE_URL

#define APR_ENCODE_URL   4

Generate RFC4648 Base 64 Encoding with URL and Filename Safe Alphabet

The problem with trying to output the entire iovec is that we cannot maintain the behaviour that a real writev would have. If we iterate over the iovec one at a time, we lose the atomic properties of writev(). The other option is to combine the entire iovec into one buffer that we could then send in one call to write(). This is not reasonable since we do not know how much data an iovec could contain.

The only reasonable option, that maintains the semantics of a real writev(), is to only write the first iovec. Callers of file_writev() must deal with partial writes as they normally would. If you want to ensure an entire iovec is written, use apr_file_writev_full().

APR_DECLARE ( const char )

Convert text data to base64, and return the results from a pool.

Parameters
pPool to allocate from.
srcThe original string.
slenThe length of the original string, or APR_ENCODE_STRING if the actual length should be computed based on NUL termination.
flagsIf APR_ENCODE_NONE, emit RFC4648 Base 64 Encoding. If APR_ENCODE_NOPADDING, omit the = padding character. If APR_ENCODE_URL, use RFC4648 Base 64 Encoding with URL and Filename Safe Alphabet. If APR_ENCODE_BASE64URL, use RFC7515 base64url Encoding.
lenIf not NULL, outputs the length of the encoding (excluding the trailing NUL).
Returns
A NUL terminated string allocated from the pool on success, or NULL if src is NULL or allocation failed or the encoding is not possible (see apr_encode_base64 errors).

slenThe length of the original string, or APR_ENCODE_STRING if the actual length should be computed based on NUL termination.
flagsIf APR_ENCODE_NONE, emit RFC4648 Base 32 Encoding. If APR_ENCODE_NOPADDING, omit the = padding character. If APR_ENCODE_BASE32HEX, use RFC4648 base32hex Encoding.
lenIf not NULL, outputs the length of the encoding (excluding the trailing NUL).
Returns
A NUL terminated string allocated from the pool on success, or NULL if src is NULL or allocation failed or the encoding is not possible (see apr_encode_base32 errors).

Convert binary data to base32, and return the results from a pool.

Parameters
pPool to allocate from.
srcThe original buffer.
slenThe length of the original buffer.
flagsIf APR_ENCODE_NONE, emit RFC4648 Base 32 Encoding. If APR_ENCODE_NOPADDING, omit the = padding character. If APR_ENCODE_BASE32HEX, use RFC4648 base32hex Encoding.
lenIf not NULL, outputs the length of the encoding (excluding the trailing NUL).
Returns
A NUL terminated string allocated from the pool on success, or NULL if src is NULL or allocation failed or the encoding is not possible (see apr_encode_base32_binary errors).

Convert base32 or base32hex with or without padding to text data, and return the results from a pool.

Parameters
pPool to allocate from.
srcThe base32 string to decode.
slenThe length of the original string, or APR_ENCODE_STRING if the actual length should be computed based on NUL termination.
flagsIf APR_ENCODE_NONE, parse RFC4648 Base 32 Encoding. If APR_ENCODE_BASE32HEX, use RFC4648 base32hex Encoding.
lenIf not NULL, outputs the length of the encoding (excluding the trailing NUL).
Returns
A NUL terminated string allocated from the pool on success, or NULL if src is NULL or allocation failed or the decoding is not possible (see apr_decode_base32 errors).

Convert text data to base16 (hex), and return the results from a pool.

Parameters
pPool to allocate from.
srcThe original string.
slenThe length of the original string, or APR_ENCODE_STRING if the actual length should be computed based on NUL termination.
flagsIf APR_ENCODE_NONE, emit RFC4648 Base 16 Encoding. If APR_ENCODE_COLON, separate each token with a colon.
lenIf not NULL, outputs the length of the encoding (excluding the trailing NUL).
Returns
A NUL terminated string allocated from the pool on success, or NULL if src is NULL or allocation failed or the encoding is not possible (see apr_encode_base16 errors).

Convert binary data to base16 (hex), and return the results from a pool.

Parameters
pPool to allocate from.
srcThe original buffer.

◆ APR_DECLARE() [3/3]

APR_DECLARE ( const unsigned char )

Convert base64 or base64url with or without padding to binary data, and return the results from a pool.

Parameters
pPool to allocate from.
srcThe base64 string to decode.
slenThe length of the original string, or APR_ENCODE_STRING if the actual length should be computed based on NUL termination.
flagsIf APR_ENCODE_NONE, attempt to decode the full original buffer, and return NULL if any bad character is detected. If APR_ENCODE_RELAXED, decode until the first non base64/base64url character.
lenIf not NULL, outputs the length of the decoding (excluding the trailing NUL).
Returns
A NUL terminated string allocated from the pool on success, or NULL if src is NULL or allocation failed or the decoding is not possible (see apr_decode_base64_binary errors).

Convert base32 or base32hex with or without padding to binary data, and return the results from a pool.

Parameters
pPool to allocate from.
srcThe base32 string to decode.
slenThe length of the original string, or APR_ENCODE_STRING if the actual length should be computed based on NUL termination.
flagsIf APR_ENCODE_NONE, parse RFC4648 Base 32 Encoding. If APR_ENCODE_BASE32HEX, use RFC4648 base32hex Encoding.
lenIf not NULL, outputs the length of the encoding (excluding the trailing NUL).
Returns
A NUL terminated string allocated from the pool on success, or NULL if src is NULL or allocation failed or the decoding is not possible (see apr_decode_base32_binary errors).

Convert base16 (hex) to binary data, and return the results from a pool.
